Howard County police were on the scene of a crash in front of Mt. Hebron High School in the 9400 block of Route 99 involving five teens Thursday afternoon. Officials said all the teens are students from Ellicott City.

Police believe the car the students were riding in, a Honda Civic, pulled out from the school parking lot around 2:20 p.m. and was struck by a very large Mack truck. The truck is owned by a tree-removal service and was traveling westbound on Route 99.

It is unknown if the Civic was turning right or left out of the parking lot.

Authorities said the Civic was driven by Jeffrey Conner Sinclair, 18. He remains in critical condition at Shock Trauma.

The other four students were taken to Howard County General Hospital with injuries that were not life-threatening, and they were later released. The front seat passenger was Justyn Richard Alexander, 17. The back seat passengers were Michael Dennis Brooks, 15; Elisha Shannon Brown, 17; and Urek Ali Bradshaw, 16.

It is unclear if any of the teens were wearing seat belts.

Police said the driver of the Mack truck involved in the crash was not injured. He has been identified as David Dell, 43, of Sykesville.

Investigators believe the Honda may have failed to stop at the stop sign exiting the school parking lot, and failed to yield the right of way to the truck.

Investigators said it does not appear that the truck was speeding. The investigation is ongoing.

In the past, the neighborhood has attempted to get a speed hump in the road. Neighbors said the intersection of the crash does not have a stop light and has always been dangerous.

Howard County school officials said it's up to county government officials to make any changes.
